Definitions
- This invention relates to an arrangement which serves to facilitate the launching of and taking aboard surface referenced systems.
- a primary use of the arrangement accor ⁇ ding to the invention is with floats adapted to carry air guns for marine seismic prospection.
- this invention is directed to a float arrangement adapted to be launched in water and to be retracted, respectively, by means of a hoist, the float being adapted to carry at least one submersible body suspended from the float by means of a wire.
- the float is provided with at least one hoisting drum for a hoist wire from the hoist, that, moreover, the float is provided with at least one suspension drum for the suspension wire.to the submersible body, that the hoisting drum and the suspension drum are rotationally coupled to each other, and that the wires are arranged in such a way on the drums that the suspension wires are reeled -in when the hoist wires are. reeled-out from the hoisting drums, and vice versa.
- submersible bodies for example in the form of air guns
- a hoist for example a telescoping boom on a seismic prospection vessel.
- the boom may then be retracted onto the deck of the vessel with the float and the air guns without having to pull these onboard over a slipway and further along the deck.
- the equipment may more easily be launched and retracted at the same time as re ⁇ ducing to a high degree the stresses imposed upon such equip ⁇ ment when pulled up from the water to the deck via a slipway or the like.
- Figure 1 schematically shows an arrangement according to the invention in side view
- Figure 2 shows a float in the arrangement, seen partly in. section from one end and at an enlarged scale.
- Figure 1 show ' s a buoy or body 10 in the form of an elon ⁇ gated float or the like which has been lowered to the water surface 100 by means of a hoist in the form of a boom 1 having hoisting wires 2 and 3.
- air guns 11, 12 and 13 have been lowered from the float 10 and are suspended in the positions shown by means of suspension wires 14, 15 and 16.
- the remaining four air guns with their wires being shown in - Figure 1 correspond completely to the above air guns 11, 12 and 13 and shall not be described in detail in the following.
- the wires 2 and 3 are detached from the boom 1 so that the float 10 may be brought into a desired position with respect to the vessel, determined-inter alia,by the length of the towing wire.
- a number of floats with associated air guns may be towed in cer ⁇ tain configurations in. order to obtain defined sound radiation patterns from the air guns as a whole.
- hoses and conduits for supplying compressed air and control signals etc. to the air guns.
- axle 4 On the float 10 there is mounted an axle 4 for example by means of bearing supports 21, 22 and 23 and the complete axle
- axle 4 may be sub-divided into two sections 4a and 4b by means of a flexible coupling 19. Such sub-division of the axle into two or more sections may be practical depending upon the total length of the axle and upon the design of the float.
- axle 4 In the first place the axle 4 carries two hoisting _ drums
- the axle carries a total of seven suspension drums of which there is here referred to the three suspension drums 7, 8 and 9 for the respective air guns 11, 12 and 13 with associated suspension wires 14, 15 and 16. From their respective drums these wires are passed through vertical channels 24, 25 and 26, respectively, in the float. It is obvious that when the drawing shows a total number of seven _air guns, this is only a pure example., since the number of air guns in such an arrangement may of course be larger -or smaller than this. In other uses it may be contemplated that it would be of inte ⁇ rest to have only one single submersible body and that it would be sufficient with one single hoisting wire. In such case the float will only comprise one hoisting drum and one suspension drum.
- suspension drums 7, 8 and 9 have the associated wires 14, 15 and 16 fully reeled-in so that the air guns 11, 12 and 13 are suspended closely underneath the float 10, i.e. in engagement with the bottom thereof.
- the hoist boom 1 has a cantilevered position with respect to the. vessel,and the float 10 is lowered by paying out the hoist wires 2 and 3.
- continued paying-out of the hoisting wires means that the air guns 11, 12 and 13 start to sink from the float 10. This causes rotation of the axle 4 so th ⁇ tt the suspension wire is reeled out from the respective drums 7, 8 and 9, whereas the hoisting wires 2 and 3 are reeled in onto the hoisting drums 5 and 6.
- the boom 1 may be retracted over the deck of the vessel and the whole equipment with float and air guns may be parked and disconnected so that the boom will be ready for the possible hauling-in of other floats with associated air guns.
- the submersible body or the air gun itself constitutes a stop member being in cooperation with the bottom of the float 10, adapted to arrest the suspension wire against continued reeling when hauling-in the float.
- Specific stop members may be contemplated for the same purpose, depending upon ⁇ inter alia,the type of submersible body con ⁇ cerned and the design of the float.
- the rotational coupling of the respective drums as shown in the drawing, is effected directly through the continuous axle 4.
- the rate of rotation and thereby the velocity of reeling-in and reeling-off, respectively, may be separately adjustable for the individual drums.
- gear trans ⁇ mission / Variations of the drum diameters may also be utilized as a means of obtaining specific velocity relationships desired for the various wires involved in the arrangement.
- an arrangement having two or more hoisting wires from a hoist means will provide for associated hoisting drums being designed for the same wire velocity. In such case it is an advantage in practice that these hoisting drums have the same diameter.
- the suspension drums When employing an elongated float as for example shown in the Norwegian patent application referred to initially, it is convenient to arrange the suspension drums with axial alignment both mutually and with respect to the hoisting drums.
- the common drum axle runs in the longitudinal direction of the float in such an embodiment.
- all wires are arranged to lie in the same vertical plane, which may be located approximately centrally of the float 10.
- Figure 2 shows more in detail the arrangement of the axle section 4b with drum 7 by means of the support 21 on the deck of the float 10.
- a suspension wire (not shown) may be passed from the drum 7 through the interior of the float 10 in the channel 24 which is open through the bottom or the keel of the float.
- suspension drums are designed with the same diameter as the hoisting drums.
